FLANGE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 542,922, dated July 16,1895.

Application filed November 20, 1894- Serial No. 529,386- (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM H. BROOK, of Brooklyn, in the county ofKings and State of New York, have invented a new and ImprovedFlange-Wrench, of which the following is a full, clear, and exactdescription.

My invention relates to a wrench particularly adapted for screwingflanges upon pipes,

ence indicate corresponding parts in all the views.

Figure l is a perspective view of the wrench, illustrating also itsapplication to a flange of a pipe. Fig. 2 is a plan view of one side ofthe wrench, and Fig. 3 is a plan view of the opposite side.

In carrying out the invention the wrench consists of a handle 10 and ahead 11. The said head is of substantially segmental construction, beingprovided with teeth 12 at each of its ends, whereby. the said head has Itwo working-faces and is therefore capable of being reversed whennecessary. In connection with the head an-arm 13 isemployed, which armis pivoted upon one side face of the handle adjacent to the head, andthe pivot of the said arm is about central with respect to the spacebetween the working-faces of the head. The arm 13 is of such length thatit extends over and beyond the outer or convexed face of the head andis-provided at its outer end with a stud let, the stud being so locatedthat the arm may be carried in direction of either of the working-facesof the head without the stud interfering with the same. The pivot-pin 15of the said arm may be either attached'to the handle or made an integralportion of the same.

The operation of this wrench is plainly shown in Fig. 1, in which itwill be observed that one toothed or working face of the wrench isplaced in engagement with the periphery of the flange A, while the arm13 is carried manner to screw it on the pipe B, and when the flange hasbeen turned as far as possible the arm is disengaged from the flange andits studis placed in the next lower bolt-hole. This operation iscontinued until the flange is properly screwed to place.

It is evident that this wrench, by reason of its two working-surfaces,may be used either right or left, and may be employed to remove a flangefrom a pipe as well as to screw one on the same.

The wrench is simple, durable, and economic, comprising practically buttwo parts, since the head and handle are made preferably from one pieceof material.

Having thus described my invention, I claim as new and desire to secureby Letters Paten-t- 1. A flange wrench, comprising a handled head, anarm pivoted thereto, and a stud projected from the arm substantiallyparallel to its pivot, the arm connecting the pivot to the stud beinglocated entirely to one side of the handle, so that when the stud isswung to either side of the handle, there will always be a free spacebetween the stud and the head to permit the tool to be engaged with aflange, substantially as described.

2. A flange wrench comprising a head having a biting face on each sideand provided with a handle and an arm pivotally connected to the headand extending beyond the biting faces and provided with a studprojecting from its free end substantially parallel to its pivot pin,substantially as set forth.

3. A flange wrench comprising a head having a lug projecting from oneface and having a biting face on each side of the lug, and being alsoprovided with a handle and an arm having a perforation to receive saidlug, the end of said arm extending beyond the end of the head and havinga stud projecting from it parallel to the said lug on the head,substantially as set forth.
